T0 aZZ 2071,0121, it may concern: I

Be it known that I, ALBERT W. PEARSALL, a citizen of the United States, residing at anhattan borough, New York city, in the county and State of New York, have invented new and useful Improvements in Receivers for Pneumatic-Despatch Tubes, of which the following is a specification.

This invention relates to certain novel features of construction set forth in the following specification and claim and illustrated in the annexed drawing, in which.

Figure is an elevation of a receiver and adjacent parts, some of them in section. Fig. 2 is a face view of Fig. 1. Fig. 3 is asectional view of a terminal portion.

The receivingterminal shown at a is adapted to receive a carrier 1), so that the latter can be reached or taken by an operator or attendant, a suitable table or counter, as indicated at 0, being usually provided counting change or other details. The carrier having traveled along the tube or delivery d and discharged from its mouth or end 6 drops or passes into such receiving-terminal. As shown in the drawing, the delivery is independent or spaced from the receivingterminal-that is, between the mouth or terminating-point e and the receiver is a break or space which, while not large enough nor so arranged as to allow the carrier to pass otherwise than from mouth 6 into receiver a, has been found effective in preventing Vibrations from the receiving-terminal a being communicated to the delivery. The carrier dropping or being arrested in the receivingterminal produces a certain amount of hammering or vibration which, if of sufficiently continued duration or of sufficient violence and communicated to the delivery, has been found, at least on certain occasions, to cause loosening of the joints or leakage, the objection of which is manifest. By having the terminal a separate or spaced from the delivery the transmission of jars or shocks is avoided, at any rate sufficiently to practically avoid such difficulty.

By having the receiving chute or terminal of open-work or suitably perforated an accumulation of carriers in such chute can be observed bythe' operator.

The removalopening of the chute a, is shown somewhat shorter than the carrier, or, rather, a lid f is shown, which when closed ordown on the chute will leave the exposed or uncovered part of such opening shorter or smaller than the carrier. A carrier dropping or shooting against the buffer 9 or coming' to a sudden stop at the terminal is prevented by lid f from jumping or bouncing out of place-as, for example, onto the floor or out of the operators reach. In lifting or taking the carrier out ofl'the terminal, however, such removal causes the lid to yield or open sufficientlyforfreeingthecarrier. This lid can be arranged to normally close by its weight or by a spring or spring-hinge, or by both agencies, if desired. In the drawing the lid is shownhinged'or jointed at 7t.

To receive theimpact of the carrier, a buffor g is provided; This buffer can be practically formed in shape of a hollow halfsphere-as, for example, one-half of a rubber ball,which furnishes an elastic and pneu matic cushion. This bufier'or cushion g can be seated on a flange i at the end of the terminal, such end being closed by a plate is, screwed or secured in place. As the buffer g rests on the terminal or on the flange 11 thereof and not on the plate is, the latter or its fastenings are not apt to work loose or be affected by the blows of the carrier.

The support 1 for the delivery and terminal can be formed by a suitable standard. The so-called suction-standard can be utilized forthis' purpose. By having both delivery and terminal on one standard or straight support said parts can be readily secured in alinement or so that the carrier will properly pass or drop from the delivery to the terminal.

A clasp or fastening m is shown for engaging the mouth part c of the delivery, and the entering part or mouth or upper portion of the terminal a can likewise be secured, as seen at 'n. Abrace or arm 0 for the terminal is also shown, said two giving a satisfactory hold.

Before the fastenings n o are tightened the terminal a could he swlveled or set with its end It pointing in any desired direction as called for by the locality in which the system is mounted-that is, while fastening it remains fixed on standard Z the terminal a could fastenings nand 0 be swiveled or set in such fastening a to point in the desired direction. The fastening 0 being then applied or clamped in place, the terminal is suitably secured or fixed.

What I claim as new, and desire to secure by Letters Patent, is

1. A receiving-terminal having a carrierremoval opening made shorter or smaller than the carrier substantially, as described.

2. A receiving-terminal having a carrierremoval opening, and a closure or lid for a portion of the said opening.

3. A receiving-terminal having a carrierremoval opening and a closure or lid for part of said opening to normally diminish the size of the latter below the size of the carrier and prevent the latter accidentally leaving the terminal substantially as described.

4. Areceiving-terminalhavingapneumatic bufier of hollow hemispherical shape and a carrier-removal opening of less length than the carrier, substantially as described.

5. A receiving-terminal having a flange, a

butter seated on the flange, and said terminal further provided with a carrierremoval opening of less length than the carrier substantially as described.

6. A receiving-terminal having a flange, a closing-plate secured at the 'fiange, and a buffer seated on the flange so as not to rest on or press against the closing-plate substantially as described.

7. In a pneumatic-despatch-tube apparatus a delivery and receiving terminal having a carrier-removal opening of less length than the carrier, and a standard ,or support made to secure said delivery and receiving terminal in alinement and out of contact with one another substantially as described.

8. In a pneumatic-despatch-tube apparatus a delivery and receiving terminal, combined with a suction-standard, said receiving-terminal and the end or mouth of said delivery being secured to the suction-standard in alinement with one another substantially as described.

9. A suction-standard combined with a delivery and receiving terminal having their delivery and receiving months or portions in alinement with but out of contact with one another, fastenings for securing said mouth portions to the standard, and a brace or fastening for the lower or removal end portion of the terminal-substantiallyas described.

10. A suction-standard combined with a delivery and receiving terminal, a fastening for securing the upper or receiving portion of the terminal to the standard, and a brace on the standard connected to the lower or removal portion of the terminal, said terminal being adapted to be swiveled or set in the fastening for causing its removal portion to extend in desired direction substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
